KITCHENER — Region of Waterloo Public Health
concluded its investigation into a hepatitis C outbreak at a Kitchener
colonoscopy clinic in late 2013.

The final report presented to a regional
council committee Tuesday said what most likely happened is hepatitis C
was spread from a previously undiagnosed client to four other patients
at Tri-City Colonoscopy Clinic on Dec. 24, 2013, when a bottle of
medication was contaminated.

"There was a lapse in infection control
related to the use of multi-dose vials," said regional medical officer
of health Dr. Liana Nolan.
